Q:How to calculate the purlin of steel structure.
The general is not overlapped on type C purlin in terms of (can Z type), so the calculation length of single purlin is usually a span of 7.5 meters (the exact value may be deducted for each end of 10 mm).
Q:Want to ask the steel structure workshop leakage, how to do? How do you do it?
In a heavy rain, on-site inspection records Water Leakage position, if the conditions can be used to view Water Leakage close status of elevator, combined with house design drawings, a detailed record of the status of Water Leakage; to stay outside after the rain stopped, the area near the roof on the view point of the situation, meet all kinds of defect parts, should be promptly recorded, also available camera file.
Q:How is the roof of the steel structure closed?
Light steel construction edge refers to the joint of two colored plates or the edge of the colored plate, through some treatment, play the role of decoration and waterproof. It is only a small part of the project cost, and is often neglected, but it plays a key role in the overall effect of the building. Some foreign companies than domestic products with competitiveness is mainly in the envelope, and the biggest difference is in the aspects of retaining edge, so the improved edge system is very important to improve our level of light step.
Q:What are the main steel structures in the steel structure and which are the secondary steel structures?
The secondary structure, or should be said that the subsidiary component, refers to the envelope of the purlin, door and window frame, generally attached with the main structure, the stress is simple and clear, the damage also has little effect
Q:What is the difference between a reinforced concrete structure and a steel concrete structure?
The reinforced concrete structure is a structure made of steel and concrete. The steel bars bear tension and the concrete bears the pressure. The utility model has the advantages of firmness, durability, good fire resistance, steel structure, steel saving, low cost, etc..Because the steel has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads, the second steel good homogeneity and isotropy, an ideal elastic body, most consistent with the basic assumption of the general engineering mechanics. Therefore, the seismic performance of the steel structure of the seismic performance of reinforced concrete structures.
Q:The longitudinal force of a steel column supported by a steel column
The 10% of the maximum wheel pressure on all brake wheels acting on one side track shall be used
Q:What is called a steel rivet?
It's going to be an antique. Aluminum or steel rivets are used for locking structures when they are used for retaining structures, not for structural purposes. As for the thin steel plate, the steel structure is not good, and at the very least, the structural professional pays little attention to rivet pulling.
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
Second mine buildings or third mine buildings for steel or reinforced concrete buildings, between the steel or reinforced connection meet the specification and use it as a lead line under the condition when the vertical pillar plays a lead role, can not meet the requirements of special spacing between deflectors the.
Q:Who knows what HW, HN and HM mean in steel structures?
Upstairs, the answer is wrong, HW refers to the wide flange, H steel, HM refers to the middle flange H steel, HN refers to the narrow flange H steel, in which the "W M N" are English, "wide", "middle", "narrow", the first letter "wide.Middle. narrow""
Q:How to consider the influence of base displacement on steel structure
A variety of raw materials will exist in a variety of deformation, steel structure in prefabricated projects will appear in a variety of geometric size deviation. Such as bending, uneven and non vertical and so on need to be corrected, correction works often use heating correction, the correction of the components will appear heating zone embrittlement of the scene. Material cutting or welding deformation often happen, such as a variety of complex twists and turns, distortion and warping deformation etc..
